PSTeams - PowerShell Module

PSTeams is a PowerShell Module working on Windows / Linux and Mac. It allows sending notifications to Microsoft Teams via WebHook Notifications. It's pretty flexible and provides a bunch of options. Initially it only supported one sort of Office 365 Connector Card but since version 2.X.X it supports Adaptive Cards, Hero Cards, List Cards and Thumbnail Cards. All those new cards have their own cmdlets and the old version of creating Teams Cards stays as is for compatibility reasons. The most fun you will get from playing with Adaptive Cards, but rest has their use case.

Links/Blogs

While I didn't spent much time creating WIKI, working on Get-Help documentation, I did write 4 articles that should help you get started. First 3 articles are for version 0.X.X-1.X.X, and last one is small introduction to new versionF.

• [x] PSTeams – PowerShell Module
• [x] PSTeams – Send notifications to MS Teams from Mac / Linux or Windows
• [x] Sending Messages to Microsoft Teams from PowerShell just got easier and better
• [x] Introducing PSTeams 2.0 – Support for Adaptive Cards, Hero Cards, List Cards and Thumbnail Cards

Supported Cards

While WebHook Notifications in theory only support Office 365 Connector Card it's possible to do more than that.

• Supported in 0.X.0 - 1.0.X
  • [x] Office 365 Connector Card - The Office 365 Connector card provides a flexible layout with multiple sections, fields, images, and actions. This card encapsulates a connector card so that it can be used by bots. See the notes section for differences between connector cards and the O365 card.
• Supported in 2.X.X
  • [x] AdaptiveCard
  • [x] List Cards
  • [x] Hero Cards
  • [x] Thumbnail Cards

Below you can find how to send them and what they display. You should be aware that while I've added some features, not all of them will work in Teams such as submitting data, or using inputs (they may display data but not really do anything). It's still work in progress and things may change and get new features.

Adaptive cards

Adaptive Cards are most advanced cards. There's lots of options available. Make sure to review:

• Adaptive Card Samples
• Adaptive Card Playground

Here's some code / output:

New-AdaptiveCard -Uri $Env:TEAMSPESTERID -VerticalContentAlignment center {
    New-AdaptiveContainer {
        New-AdaptiveColumnSet {
            New-AdaptiveColumn {

                New-AdaptiveTextBlock -Weight Bolder -Text 'SHADES' -HorizontalAlignment Center
            } -Width Auto
            New-AdaptiveColumn {
                New-AdaptiveTextBlock -Text "Sat, Aug 31, 2019" -HorizontalAlignment Center -Wrap
                New-AdaptiveTextBlock -Text "Final" -Spacing None -HorizontalAlignment Center

                New-AdaptiveTextBlock -Weight Bolder -Text 'SKINS' -HorizontalAlignment Center
            } -Width Auto -Separator -Spacing Medium
        }
    }
} -Speak 'The Seattle Seahawks beat the Carolina Panthers 40-7'

List Cards

Here's a simple way to send List Cards to Teams using WebHook

• List Items do not support tapType imBack. When clicked action is not taken
• List Items do not support tapAction. It's there, but doesn't work.
• List Items do not support type file. It displays, but no action is taken. It's better to use resultItem

Code

New-CardList {
    New-CardListItem -Type file -Title 'Report' -SubTitle 'teams > new > design' -TapType openUrl -TapValue "https://contoso.sharepoint.com/teams/new/Shared%20Documents/Report.xlsx" -TapAction editOnline
    New-CardListItem -Type resultItem -Title 'Report' -SubTitle 'teams > new > design' -TapType openUrl -TapValue "https://contoso.sharepoint.com/teams/new/Shared%20Documents/Report.xlsx"
    New-CardListItem -Type resultItem -Title 'Trello title' -SubTitle 'A Trello subtitle' -TapType openUrl -TapValue "http://trello.com" -Icon "https://cdn2.iconfinder.com/data/icons/social-icons-33/128/Trello-128.png"
    New-CardListItem -Type section -Title 'Manager'
    New-CardListItem -Type person -Title "John Doe" -SubTitle 'Manager' -TapType imBack -TapValue "[email protected]" -TapAction whois
    New-CardListButton -Type openUrl -Title 'Show' -Value 'https://evotec.xyz'
} -Uri $Env:TEAMSPESTERID -Title 'Card Title'

Output

Hero Cards

Here's a simple way to send List Cards to Teams using WebHook

• Hero Buttons (New-HeroButton)do not support button type other then openUrl
  • When using Type imBack action is not taken
  • When using Type file button is not displayed
• Using more than 3 buttons causes carousel for card. I've blocked it out, as all that happens is text is doubled/image is doubled but buttons don't show up over 3

Code

New-HeroCard -Title 'Seattle Center Monorail' -SubTitle 'Seattle Center Monorail' -Text "The Seattle Center Monorail is an elevated train line between Seattle Center (near the Space Needle) and downtown Seattle. It was built for the 1962 World's Fair. Its original two trains, completed in 1961, are still in service." {

Thumbnail Cards

Here's a simple way to send Thumbnail Cards to Teams using WebHook

• Images are not supported in buttons, you can send them but it's not displayed
• imBack action is not supported in buttons, you can send them but once you click it an notification message appears

Code

New-ThumbnailCard -Title 'Bender' -SubTitle "tale of a robot who dared to love" -Text "Bender Bending Rodríguez is a main character in the animated television series Futurama. He was created by series creators Matt Groening and David X. Cohen, and is voiced by John DiMaggio" {

• When executed from Linux

• When executed from Windows

• When executed from MacOS

• And this is more advanced option sent by PSWinReporting

Installing/Updating on Windows / Linux / MacOS

Installation doesn't require administrative rights. You can install it using following:

Install-Module PSTeams

But if you don't have administrative rights on your machine:

Install-Module PSTeams -Scope CurrentUser

To update

Update-Module -Name PSTeams

That's it. Whenever there's a new version you simply run the command and you can enjoy it. Remember, that you may need to close, reopen the PowerShell session if you have already used the module before updating it. The important thing is if something works for you on production, keep using it till you test the new version on a test computer. I do changes that may not be big, but big enough that auto-update will break your code. For example, small rename to a parameter and your code stops working! Be responsible! Dependencies: PSSharedGoods, PSWriteColor and Connectimo are only used during development. When published to PSGallery / Releases it's a merged release without any dependencies.
